Background and Study Aim: To evaluate the state of preparedness of top athletes, specific tests are recommended as the specificity principle is paramount in competitive sports. The main objective of this study was the discriminant and factorial validity of four judo-specific tests in a sample of high-level junior female judokas.

Matherials and Methods: Fourteen Croatian junior female judokas (range 17-19 years of age) took part in the study. They were divided into two groups – seven elite judokas with body mass 71.0 ±20.8 kg, height 170.9 ±4.6 cm, judo practice 8 ±1.2 years and seven sub-elite ones with body mass 72.8 ±19.7 kg, height 169.3 ±4.6 cm, judo practice 6 ±1.4 years. The following judo-specific tests were investigated: the Special Judo Fitness Test (SJFT), the Uchi Komi Fitness Test (UFT), the Santos Test (ST) and the Ten-Station Judo Ability Test (SJA).

Results: The Student's t-test for independent samples indicated statistically significant difference (p< 0.05) between the elite and subelite female judokas in SJFT and UFT. The magnitude of the differences between the two groups was large when the performance in the SJFT, UFT and ST are considered and moderate when the SJA is analyzed. Moderate-to-high and statistically significant correlation coefficients between all the tests were obtained, and with factor analysis only one significant component has been extracted.

Conclusions: The SJFT and UFT better discriminated the elite from the subelite female judokas and, therefore, are suitable for the evaluation and monitoring of the training status of female high-level junior judo athletes. All four judo-specific tests have a similar measurement objective.
